CYP17A1 and polycystic ovary syndrome: And relative expression of IL-15 was positively correlated with CYP17A1 in cumulus granulosa cells of PCOS patients and age-matched control (r=0.7904, P=0.0254, Figure 1E) and relative expression of IL-2rg (IL-15r) was positively correlated with CYP17A1 in cumulus granulosa cells of PCOS patients and non-PCOS women (r=0.5849, P=0.0458, Figure 1F) by using bioinformatics analysis.
